Software equivalent to Fluke Net tools

Hi All. I have seen fluke net tools in action. I can use cpd to see what port a cable is connect to and tell the length of a cable as well as help to detect faults. Is the a software ( preferable open source!) that can do the same? Please let me know.

You may be able to find a CDP reader out there for open source, but for the
cable testing, that is where you need the right hardware. A standard NIC
isn't built to do cable length and cable faults. That's why those hardware
tools are necessary.
